General Description
The EL2245C and EL2445C are dual and quad versions of the popular EL2045C. They are high speed, low power, low cost monolithic opera t i o n a l amplifiers built on Elantec's proprietary complementary bipolar process. The EL2245C and EL2445C are gain-of-2 stable and feature a 275V/µs slew rate and 100MHz bandwidth at gain-of-2 while requiring only 5.2mA of supply current per amplifier. Th e power supply operating range of the EL2245C and EL2445C is from ±18V down to as little as ±2V. For single-supply operation, the EL2245C and EL2445C operate from 36V down to as little as 2.5V. T h e excellent power supply operating range of the EL2245C and EL2445C makes them an obvious choice for applications on a single +5V or +3V supply. T he EL2245C and EL2445C also feature an extremely wide output voltage swing of ±13.6V with VS = ±15V and RL = 1k. At ±5V, output voltage swing is a wide ±3.8V with R L = 500 and ±3.2V with RL = 150. Furthermore, for single-supply operation at +5V, output voltage swing is an excellent 0.3V to 3.8V with RL = 500. At a gain of +2, the EL2245C and EL2445C have a -3dB bandwidth of 100 MH z with a phase margin of 50°. Because of their conventional voltage-feedback topology, the EL2245C and EL2445C allow the use of reactive or non-linear elements in their feedback network. This vers atil ity combined with low cost and 75mA of output-current drive m ake the EL2245C and EL2445C an ideal choice for price-sensitive applications requiring low power and high speed.

1. Slew rate is measured on rising edge. 2. For VS = ±15V, VO UT = 20VPP. For VS = ±5V, VOU T = 5VPP. Full-power bandwidth is based on slew rate measurement using: FPBW = SR/(2 * Vpeak). 3. Video performance measured at VS = ±15V, AV = +2 with 2 times normal video level across RL = 150. This corresponds to standard video levels across a back-terminated 75 load. For other values of RL, see curves.
